Aptos Capture The Flag

This report is a detailed CTF write-up covering five Aptos/Move challenges (CheckIn, HelloMove, SimpleSwap, SwapEmpty, MoveLockV2). It explains each challenge's mechanics, the vulnerabilities or puzzles leveraged (hash preimage checks, discrete logarithm solving, AMM swap reward and slippage abuse, unchecked bit shifts, and transaction-context-dependent encryption), and the methods used to solve them, including scripts, algorithmic approaches, and mock-module techniques to trigger in-chain flag events.
